erofs: allow empty device tags in flatdev mode

2023-10-10T20:02:59Z

[ Upstream commit f939aeea7ab7d96cd321e7ac107f5a070836b66f ] Device tags aren't actually required in flatdev mode, thus fix mount failure due to empty device tags in flatdev mode.

erofs: drop unnecessary WARN_ON() in erofs_kill_sb()

2023-08-01T08:12:24Z

Previously, .kill_sb() will be called only after fill_super fails. It will be changed [1]. Besides, checking for s_magic in erofs_kill_sb() is unnecessary from any point of view. Let's get rid of it now.

block: replace fmode_t with a block-specific type for block open flags

2023-06-12T14:04:05Z

The only overlap between the block open flags mapped into the fmode_t and other uses of fmode_t are FMODE_READ and FMODE_WRITE. Define a new blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and ->ioctl and stop abusing fmode_t.

block: use the holder as indication for exclusive opens

2023-06-12T14:04:04Z

The current interface for exclusive opens is rather confusing as it requires both the FMODE_EXCL flag and a holder. Remove the need to pass FMODE_EXCL and just key off the exclusive open off a non-NULL holder. For blkdev_put this requires adding the holder argument, which provides better debug checking that only the holder actually releases the hold, but at the same time allows removing the now superfluous mode argument.

block: introduce holder ops

2023-06-05T16:53:04Z

Add a new blk_holder_ops structure, which is passed to blkdev_get_by_* and installed in the block_device for exclusive claims. It will be used to allow the block layer to call back into the user of the block device for thing like notification of a removed device or a device resize.

erofs: adapt managed inode operations into folios
